Client Tab

Prerequisites

You have created and configured an MQTT source system.

Procedure

1. Select an MQTT source system in the Client field.

   All the settings are adopted from the selected MQTT source system. (See also: MQTT Source System: Client Tab.)

2. If you choose Navigate to the Client, you can navigate to the MQTT source system and change the settings there.

3. Change the ID in the Client ID field, if necessary.

   The Client ID field can be edited; that is, you can overwrite the client ID that was copied over from the source system. If you change the ID, the connection to the MQTT server cannot be shared. The decision about whether or not you should change the client ID depends on the specific scenario. A connection to the MQTT server can only be shared by MQTT destination systems that are used by the same agent instance and have the same client ID.

   Alternatively, you can leave the field blank. In this case, PCo creates a new client ID when the connection is being established. This makes sense if multiple connections are to be made to MQTT servers, and ensures that the client ID is unique in each case. If you enter a client ID manually, you must ensure that the ID is unique for each broker instance.
